.Be it known'that I, Gos'rwrcne lMAR-j SHALL, a citizen of the United States, residj to absorb, the concussion ing at Nampa, Idaho, have invented certain new and useful Improvements in llorse shoes, of which the following is a speeification. I p I My invention relates to horse-shoes and is 1 designed to l'urnish ashoe with an elastic heel for use on hard roads and'paved streets 1 and thus protect the boots 1 sell-cleaning, preventing the parts 'wltlrthe spring call; removed on one so as to bridge Spring supported ealks have 'heretolore j been proposed, but it is the ainr'ol' my ii'lVBIk tion to provide a specially constructed de- 1 Vice which shall be supported so as to, be. durable and of such a construction as will be,

will thus be'seen that the spring heel is not only supported where it is joined to the shoe proper, but it is also fully supported at its ex-- treme outer end and has a bearing in the up and down movement on the rounded end of the shoe to which the end of the heel corit partially incloses. The up and down, movement keeps the parts free from dirt and gives a bearing in all posi. tions of the spring heel. As the full weight the heel it is not onlydepressed, butlengthened and finds a bearing at the base or. up er end of the in clined end of the shoe, and as the pressureis taken oil, es in the lilting of the hoof, the spring exerts itself and is se arated from. the s roe proper slightly and int 1e natural short.- ening of the spring it finds a hearing toward the lower end of the inclined wall of the shoe. The con'strrurtion ol the cut-aweyportion is such as to prevent any accumulation of dirt at this point as the up and down movement of the spring,

part in connection with the ridge and the inclined cut-away parts will 76 i keep everything clear at this point and thus there is nothing tointerfere with the perfect What l claim 1szhaving a permanent sup )ort at oneend', an upwardly inclined laterally rounded support [oi-its opposite end, the springpart corre spending to its support and in'ciosing the same, substantially as described. j 2. A horse shoe having rounded inclined ends combined with a spring heel or calk having a tread intermediate of its ends, its free end conforming to\ the end of the shoe substantially as described.
